` `My'present invention relates to' cleaning devices, and `more "particularly to a novel `and improved device for cleaning the rolls land` `3`ylinc`lers of a carding machine.

` Carding machines, as is `vvell known, comprise a plurality of contiguous cylinders, drummer rolls, covered With clothing, said `clothing `comprising 'usually a plurality of bent Wire teeth Whichare set closely in rows in apiece of leather or other suitable ma- `terial and fastenedto the rolls orcylinders.

The purpose of these machines is to clean and `disentangle material such as Wool, cotton, flax, and the like, collecting together all fthe fibres, of Whatever i length, `and straightening the same for subsequent use.

Duringthe carding operation, the various rolls and cylinders, such as the main cylini ders, doffer rolls, stripper` rolls, Worker rolls, zo

jandfancy rolls, collect, dust, dirt, lint, and other foreign matter, which prevent the card clothing from performing its functions on the various rolls with full efficiency.

An important object of the present inven- "tion, therefore, Vresides in the provision of means to clean the card clothing on various rolls.

Another object of the invention resides `in the provision of means which Will accomplish thiscleaning operation during the Y continuous" operation of the carding niachine, Without interrupting the Work of said machine. l

" Another object of the invention resides in providing a` cylindrical brush having bristles,` preferably of Wire, set tangentially therein, and in providing means to rotate and simultaneously reciprocate said brush during the operation of the carding ma- `Another object of the invention resides in the particular means foreffectingthe reciprocation of the brush during its rotativeclelaning movement.

and advantages, Will be `hereinafter more fully pointed out, described and claimed.`

Referring to thedravvings, illustrating a preferred embodiment of the` present invention, v

` Fig. 1 illustrates diagrammatically a carding machine with my novel cleaning roll positioned in operative relation With several of the individual rolls of the machine; f

Fig. 2 is a side elevation of the cleaning` Fig. 7 is a cross sectional `view on the line Y 7 7 of Fig. 3; and

Fig. 8 isa fragmentary cross sectional view on the `line 8-8 of Fig. 3.

n Referring novv to the drawings, for a particular description of the invention, itslconstruction and operation, there is shovvir diagrammatically a carding "machine, Vthe framework anddriving belts of which have been omitted for the sake ofclearness, and in this drawing 10 designates a main cyl'- inder rotating in the direction of its arrow and at any desired speed, this main cylinder being mounted f or rotation on ua shaft 11.

Mounted parallel to the shaft 11 is a shaft 12 on Which is mounted a stripper roll 13, the ,cylinder 10 and stripper roll`13 each beingcovered with conventional card cloth designated generally at 14, the cards or Wires being in engagemenuas clearly illustrated in Fig. 1. i

Also parallel With the shaft 11 vand With the shaftclQ isl a shaft 15 on `which is mounted a Worlzerroll 16 covered with card cloth Which is in Contact With thebloth on `the cylinder lOand roll 13. Spaced from kso' the vvorkerroll 16 is a fancy roll 17 mounted `on a shaft 18 andcovered also with card clothing, which clothing is in engagement with the card cloth on the cylinder 10 and with similar cloth on a stripper roll 19 mounted on the shaft 20. An intermediate doffer roll 21 is mounted on a shaft 22 and the card clothing of this intermediate doffer roll is in engagement with the clothing on the cylinder 10 as well as on another adjacent main cylinder 23 mounted on the shaft 24. Two sets of stripper rolls 25 and worker rolls. 26 are provided in engagement with the cylinder 23, as well as a fancy roll 27 and cooperating stripper roll 23. A finisher doffer roll 29, covered with card cloth in engagement with the cloth covering the cylinder 23 is also provided, mounted on the shaft 30.

Each of the cylinders and rolls illustrated in Fig. 1, and above briefly described, rotates in the direction of its respective arrow shown thereon, and at speeds which have been predetermined to accomplish the results desired. n

The operation of the carding machine illustrated is simple, and will be readily understood, being briefly described as follows.

As material, such as a web of fleece, is fed to the main cylinder 10, at the left of Fig. 1, it is caught by the clothing on said roll and fed therearound. As such material passes under the stripper roll 13, it will be raised to the outer edge of the cloth on the cylinder 10. In such position it will encounter the cloth on the worker roll 16, which will pick said material from the cylinder 10 and feed it in the direction of the arrow on the Vworker roll 16. The stripper roll, however,

is rotating at a much faster rate of speed than the worker roll 16, and the card cloth on the stripper roll 13 will therefore take the material from the worker roll 16 and return it to thev cylinder 10, this operation being continuons. i

As the fibres of the material beingoperated upon become straightened out, or partially straightened ont, they will be carried by the card cloth 14 on the cylinder 10 until reaching the fancy roll 17, which will have a. still further straightening effect upon the fibres of the material, and after passing the fancy roll 17, the material will be picked up by the card cloth on the stripper roll 19, from which it will be taken vby the card cloth on the fancy roll 17 and returned to the cylinder 10. From the cylinder 10 the card cloth 31 on the intermediate doffer roll 21 will take the material and transfer it to the card cloth 32 on the cylinderv 23. The material will pass through the same operations with the' stripper rolls 25 and worker rolls 26 as above briefly described with relation to the stripper roll 13 and worker roll 16, and will also be treated by the fancy roll 27 and stripper roll 28 in the same manner as described with relation to the fancy roll 17 and stripper roll 19.

After passing the final stripper roll 28, the material will be removed from the cloth 32 by the cloth 33l of the finisher doffer roll 29, whence it will be removed in any desired manner for subsequent operation.

It will be appreciated, that during the carding operation, the card clothing on the various cylinders and rolls will accumulate dust, dirt, lint, and the like, which will interfere with the properl functioning of the said card clothing, unless such foreign matter is removed. l therefore provide my novel cleaning apparatus, and associate the same with as many of the cylinders or rolls as desired, said cleaning device operating upon a cylinder or roll at a line along which no material is fed during the carding operation, so that any material removed by my novel cleaner will be simply in the nature of waste or foreign matter.

In Fig. 1 I have illustrated a cleaner associated with the cylinder 10, another with the cylinder 23, another with each of they dofier rolls 21 and 29, and one associated with each of tue worker rolls 16 and 26.

It will be appreciated, however, that I may dispense with or add as many of these cleaning devices in a given carding machine as may be deemed desirable or necessary.

Each of the cleaning devices is identical, with the possible exception of its supporting bracket, and therefore a description of one cleaning unit will suffice for all.

My novel cleaner comprises a Wheel 34 comprising a hub and cap 36 provided with inturned flanges 37 to secure in place the leather 38 or other material in which the cleaning bristles or wires 39 are imbedded.

A key 40 is Jfixed in the hub 35 by screws P 41, the cap 36 being fixed to said hub by the screws 42 as clearly illustrated in Fig. 5.

The wheel 34 is mounted upon a shaft 43, the key 40 riding in the keyway or slot 44 formed in said shaft. The hub 35 is provided with an annular groove 45, in which is seated the yoked end 46 of a bi'ush wheel arm 47, the yoke 46 being held in said groove by a cap 48 fixed'to said yoke by bolts 49. The outer end of the brush wheel arm 47 is yoked, as illustrated at 50, and rides on the vflanges at the open side of a channel member 51.

Rotation is imparted to the shaft 43 by means of a belt 52 engaging the pulley 53 on said shaft. Said belt is driven by a pulley 54 fiXed on the shaft 55 to which the fancy roll 27 is also fixed. rFhus, the brush wheel 34 will rotate within the yoke 46 and cap 48, since the arm 47 is restrained from rotation by its yoked end 50 on the channel guide 51.

The shaft 43 is mounted in bearings 56 carried by brackets 57, said brackets 57 being liXed to the upper reduced ends of'posts 58 by set screws 59. The posts 58 are CII 49 95, said plate being fixed to the channel 51 clamped in split sleeves 60 fixed to or an integral part of brackets 61 which in turn are fixed to the frame 62 of the machine by bolts 63, or the like. Bolts 64 are utilized to clamp the open sides of the sleeves, these bolts being positioned in bosses 65 on said sleeves. The brackets 57 have upturned ends 66, towhich the channel guides 51 are fixed by screws 67. An adjusting screw 68 threaded through a boss 69 on the bracket 61 serves to adjust the` height of the posts 58 as desired. i j

Fixed to the channel frame 51 by screws 70 is a casing 71 through which extends a shaft 72l having bearings in the journals 73 of said casing and longitudinal movement of said shaft being restrained by collars 74. The shaft72also has a bearing in a journal 75 fixed to the channel member 51 by screws 76. Adjacent to the free end of the shaft `72"is fixed a sprocket l77, a ldrive chain 78 running over said sprocket and also overa sprocket 79 mounted on the shaft 8O,` said shaft 80 carrying one worker roll 26 and being supported in a bracket 81. Within the casing 71, and fixedV for rotation with the shaft 72 is a `worm82 in mesh with which j Fig. e.

i "is a wormjgear 83 fixed toa shaft 84 by a pin 85, the shaft 84 having a bearing in the journal 86 projecting laterally from the casing 71 and having a reduced end 87 to which a sprocket 88 is `fixed by means of the pin 89 projecting through the hub 9() of said sprocket and the reduced end 87 of the shaft 84. `Running over the sprocket 88, which is housed within the channel 51, is a chain 91, said chain also` passing over a sprocket 92 mounted on a shaft 93 which hasa bearing in the journal 94 projecting from the plate by screws 96 and a collar 97 preventing longitudinal displacement of the shaft 93.

The channel 51 kis provided with an elongated slot 98 through which the shaft 93 passes,v and the plate 95 is provided with a plurality of elongated slots` 99 through whichthe stems of the screws 96 project, thus permitting movement of the sprocket to loosen or tighten the chain 91 as desired.V

The chain 91 is provided with a pin 100 which rides in a vertical slot 101 in the brush wheel arm 47, as clearly illustrated in Thus, as the worm gear 83 is rotated, rotating the sprocket 88, the chain 91 is set in motion, and will carry with it the wheel arm 47. When the wheel arm 47 reaches left, as illustrated in Fig. 3, the pin 100 will ride down in the slot 101 and upon commencing its return movement will draw the arm `47 therewith. Simultaneously with brush a combined rotary and reciprocating movement. i

It will be apparent, from a glance atFig.

5 that the ,wires or bristles 39 areset in the leather backing 38 tangentially with respect to the radius of the brushwheel 34,1and will thus impart to the card roll or cylinder with which it is associateda brushing action, the bristles 39 being so arranged with respect to the Wiresof thecard cloth as to reach substantially through said wires to effect a thorough cleaning and brushing thereof.

Since my novel device is operated during the actual operation of thecarding machine, the cleaning ofthe various rolls and cylinders is effected without any interruptionof operation of said machine, an advantage `which will be instantly apparent to those skilled inthe art.

j The simplicity, ruggedness, efficiency, and

other advantages of my novel cleaning devicewill also be evidentto those skilled in this particular art. i i

While I have necessarily described `my present invention somewhat in detail, it will `be appreciated tliatI-may` vary the size,

shape, and arrangement of` parts, Within reasonably `wide limits, without departing from the spirit ofthe invention.` i
